You need to learn a little about different digital audio format.
1. There are two standard sample rates for audio files: CD audio which is 44,100 CPS, and sound for video, which is typically 48,000 CPS. This is how often the sound is sampled. Each sample is one 16 bit number. If you look at a .WAV file, you should see it listed at 1411kbps.
2. if the MyPin converts to MP3 right off the bat, make darn sure you are using the highest available bit rate (probably 320k). MP3 is called a "lossy" compression. Its not like something like ZIP or RAR compression, where you can recover all the original data. MP3 Bit rate has nothing to do with the sample rate of the audio file.
3. MP3 processing takes the standard wave file that has been digitized, and starts to throw away data that has been deemed inaudible. The lower the bit rate, the more data that is thrown away, and the more the sound is affected. A wave file of a typical song might be 30MB in size, in MP3 at 128k, it might be 3.5MB. Some of that compression is like doing a "zip", but the rest is special sound shaping. Once the data is thrown away, you'll never get it back.
I dont know which MyPin device you have. It seems they make a dozen different ones. When your device records, if it is set to audio, it probably is reading 44.1K, if you are doing video capture it will be 48K.
If nothing else, you should be able to sample a noise profile once the file is loaded and use that. You don't need to save a noise profile, you just need some silence.
As I said before, if it's just so you can share it, I would just chop them into individual songs, do a fade out at the end if you want, and save each. I've done is dozens of times. Then you can burn an audio CD, or put them on a flash drive, or put them on something like Dropbox to save with your buddies.
